# ./configure --enable-ipv6 --with-socks
#   configure: WARNING: IPv6 is incompatible with socks, disabling IPv6 support
# We can't build a single binary with both. So what we do here is build
# 2 binaries (tnftp.ipv6 and tnftp.socks), symlink the ipv6 one to
# /usr/bin/tnftp, and tell the user he can call the socks one by name,
# or replace the symlink.

# These configure options are used for both builds. A word about libedit:
# --enable-editcomplete enables linking with the system libedit (if it
# exists). If there is no system libedit, it builds and links with the
# bundled libedit in the tnftp source. To avoid nasty surprises
# caused by libedit changes (since libedit is not one of my builds),
# I'm going to force it to use the bundled libedit. The disadvantage
# is that it doubles the sizes of the binaries, but they're still well
# under 1MB each.
